To all whom it may concern: 7

Be it known that I, JAY VAN TUYL DAN IELS, acitizen of the United States of America, residing at Hotel Russell, Russell Square,

Bloomsbury, London, En land, have inventis a view looking toward the left of Fig. l of the extreme left end of the mechanism thereof. Fig. 3 is a view similar to Fig. 2 of a slightly-modified form of construction whereg in the plate may have its eccentricity varied at will and in which instead of a contactplate to be applied to theportions of the body to be massaged a ball is used, and Fig. 4 is a top plan view of the form of construction shown in Figs. 1 and 2.

Referring to the drawings, the referenceletter a designates a frame, usually of the form shown, carrying at one end the handle I) and having rigidly secured to the other end and extending at right angles therefrom the stem or rod 7', to the lower end of which is se cured the contact-plate k or the contact-ball r, as may be desired, either of which may be of any suitable material, form, or size, but usually of about those shown. A spindle g, provided at the inner end with a beveled gearwheel f and the other with a boss g, extends longitudinally of the outer end of the frame a withinthe same and is revolubly mounted in suitable bearings, and upon the outer end of this spindle is rigidly and eccentrically mounted the eccentric-wheel h, secured upon the spindle by means of the milled thumb} nut 71.

When desired, as shown in Fig. 3, the wheel h is provided with a slot 0 to receive the spindle g, and a wing thumb-nut is used in place of'the round milled thumb-nut t, and by this arrangement it will be seen that the eccentricity of the wheel h and the consequent vibratory'force exerted upon the rotation may be easily and quicklyvaried within wide limits.

Mounted in the frame a is a pinion d, tactil ating a beveled gear-wheel e, meshing with the like beveled gearwheel f, secured to the .spindle g, and meshing with the pinion d is a spur gear-wheel c, loosely-mounted upon a shaft rotated by a handleglor in any other desired manner, whicl'l spuriigearewheel' c is saged and pressed firmly down upon the body,

the pressure of course varying with different diseases to be cured and the particular portion of the body to be operated upon. While being so held the crank Z is rapidly rotated ,Jso' as to bring aboutrapid rotation ofthe flywheel h, and this being eccentric to the axis of its rotation, and consequently of greater weight on one side than upon the other, it will be seen that a series of trem-ulous vibratiohs will thereby be transmitted by way of the plate k or ball 1" to that ortion of the body of the patient with whic the same are in contact.

In some cases instead of an eccentricallymounted wheel h the same may be axially or centrally mounted upon the spindle g, but

made of greater weight upon one side than upon the other, whereby the same practical vibratory movement will be upon rotation transmitted to the contact plate or ball.

What I claim, and desire to secure by Letters Patent, is

1. A vibrating machine for massaging purposes comprising a frame, a spindle journaled therein, a disk carried solely by the said spindle and having its center of gravity to one side the axis of the spindle, and means for driving the spindle to vibrate the frame for imparting vibrations to the body.

2. A vibratory machine for massaging purposes comprising a frame, a spindle journaled therein, a disk carried solely by the said spindle, means for adjusting the center of gravity of said disk in relation to the axis of the spindle and means for driving the spindle to vibrate the frame for imparting vibrations, to

the body. 3. A vibrating. machine for massaging purposes comprising a frame, a contact plate or icali n cr 'ibc neckline, & ramb- V wreaunto set 1 :y Jence 0f two "vntness a.
